HAEERS E.

To all Lo/0m may concern Be it known that l, llnnms ll. ll'oLT, residing :it Dormont, in the County of fllegheny :mrl State of -Pennsylvnnn a-eitizen ol the UnitedStates, have invented or rlie Covered certain new and useful l'nprmfements in Tube-Cleaners, ol' which improve ment the following is o speeilcaion.

' y .invention relates to holler tulle eleaners, comprising n head mlnptool to he rotated by a suitable motor :incl armeni with cutter ends; sind the object thereof is to provide n cleaner which will he simple in construe tion and eeetive .in operation.

A furtl'ler object of my invention to no vide a. cleaner the several parts of whieh will not, due to the vibration during its In the accompanying drawing, which' forms part of my specification, l have illsistrated the preferred embodiment of my in* vention.

Figure l is a longitudinal. .sectional View taken on the line .l l, Fig. 2; and Fig. 2 transverse sectional View taken on the line H H, Fgflf.

Like numerals are used to designate like psu-ts.

Referring to the drawing, the cleaner eomprises a two part @err-ier l, 25. each part being provided with e cutter hond. 3, Enola. e'nrrler portion has n general Cylindrical a, plnneheecl plate 5. The carrier portion l forme the rear eno. of the cleaner, and is provided with n screw threnrlefl hole 6 nclnptefl to receive the rotatable shaft of a rotary motor, Wllieh is usually employed for the operation or such Cleaners; While the e-rrer portion 2, which forms the front end of the Cleaner7 is provided With im. integrally formeel enttng tooth 'E'.

ln order to connect the two carrier portions together, so that the 'rapid vibration of the cleaner during its operation will not loosen such connection, l form screw threadecl holes iin the central portion of each plete 5; and insert therein n screw 8, prelerahly olf such length :is to extenzl through' hut not ln threading the together in such position that the open. giclee of the recesses l are on flinmetrienlly opnemen-e elllen o'l thenxls oli' rotetion The @zittern Specmtela of Letters Patent. nppumion me@ #une m, 1913.

Also, such construction j orilfs carrier comprising o lnii'lirnxnn rmni` loer of parte, and one 'whereof the oper tl effects n tightening rather thon loosenin. of its Several parte.

The Cutter-heads ere 'pr fernhly e 7linclrl eel or ring-slmed n'lernhers 9 'iro their @he nl surface 'with teeth. finch hezul is rot-ata l upon n cylindrical [is rotatably mounted l hole in the block through which the spnflle I extends' being eccentric with relation to the :uns ol? the block.

The spindle-healing holenat tno eentml por-lion of the Carrier L are formed hy drilling hel-es tl'irough the platee 5, the Spindles being inserted throngla than@ holes; and retaiized .in 'position hy the plate 5 of t )e opposite carrier.
